SIDE HARROW.

SPECIFICATION formingpart'of Letters Patent No. 651,282, dated June 5,1900. Application filed November 29, 1899. Serial No. 738,712. (No modemT0 66 whom it may concern:

Be it known that I, THOMAS RILEY WALLIs, acitizen of the UnitedStates,residing atLouisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements in SideHarrows; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which itappertains to make and use the same.

My invention relates to side barrows, and particularly to theconstruction of the frame; and it consists of a frame composed of twopieces which are bent into proper shape to form the general shape forsaid frame, said pieces overlapping or extending side by side along oneside of the frame, so as to form space-connecting bars for theattachment of the teeth and to provide for the vertical and lateraladjustment thereon.

The invention also consists in certain other details of construction, aswill be hereinafter described and specifically claimed.

In the accompanying drawings, Figure 1 is a perspective View of a sideharrow constructed in accordance with my invention. Fig. 2 is anenlarged detail perspective View of a portion of the frame upon whichthe teeth are secured. Fig. 3 is a detail perspective view of one of theteeth, showing its manner of attachment to the bars. Fig. fis a top planview of the same. Fig. 5 is a vertical section through one of the teethand clamping means, and Fig. 6 represents detail perspective views ofthe difierent parts for securing the teeth in position and permittin,

of their adjustment.

l in the drawings represents the frame of my improved side barrow, whichconsists of two metal pieces 2 and 3, the piece 2 being bent intotriangular form, with its apex slightly rounded, as at 4, and the piece3 bein g also bent into triangular form and having one of its sides, as5, extending parallel with one of the sides 6 of the piece 2 and havingone of its ends connected to one of the ends of the piece 2, as at 7, bymeans of bolts and nuts, as clearly shown, which forms the forward orfront end of the frame. The other ends of the pieces constituting theframe are left disconnected exceptwhere they are joined by means of thedevices for securing the teeth imposition, as will be hereinafterdescribed. Sufficient space is left between 'the'sides 5 and 6 of thepieces 2 and 3 to permit of the insertion of the teeth 8 and alsoforclamping-blocks 9. One clamping-block is provided for each tooth, andsaid clamping-block is provided on one of its faces with a groove orrecess 10, which receives the side bar 6 of the piece 2, the flanges ofthe clamp ing block or piece resting 011 the upper and under sides ofthe said bar. The upper and lower edges of the clamping-block 9 areprovided with recesses 10 and 11, in which the-members of a U-shapedclip 12 are seated. This U-shaped clip incloses the side pieces 5 and 6on top and bottom and is provided with screw-threaded ends to receivenuts 13.

A plate or strip 14 is interposed between the nuts and the side bar 6,as is clearly shown. From this construction and arrangement it will beseen that by unscrewing the nuts 13 the U-shaped clip can be loosenedand the tooth can be raised or lowered to different positions or can heslid along to any point desired on the side bars 5 and 6 and then thenuts tightened up, so as to secure the tooth in such position. It is ofcourse obvious that the teeth can be adjusted to any place on the bars 5and 6 without being raised or lowered, and vice versa.

With my construction and arrangement I produce a very strong, light, andsimple side harrow which is very efiective in its construction andoperation and which secures a means of supporting the teeth betweenparallel bars and also permits of the teeth being adjusted eithervertically or laterally independently of each other and of a singletooth to be removed and another tooth put in its place. I consider theconstruction of the frame composed of only two pieces and so bent as togive the frame the proper shape and at the same time secure spaced barsat one side of the frame for the attachment of the teeth a veryimportant feature of my invention, irrespective of the manner in whichthe teeth are secured in position on the frame.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A harrow comprising in itsconstructiou a triangular frame, composedof two pieces, which are bent into proper shape to form the said frame,the pieces along one of the sides being spaced apart and the forwardends of the pieces being secured together, and teeth secured between thedouble or spaced portion of the frame, substantially as described.

2. A barrow comprising in its construction a triangular frame composedof two pieces, which are bent into angular shape to form the said frame,the pieces along one side of thefranie being parallel and spaced apart,and the forward ends of the pieces being secured together, and teethsecured between the double or spaced portion of the frame in such amanner as to permit of their adjustment, substantially as described.

3. A harrow comprising in its construction a triangular frame, composedof two pieces,

which are bent into angular shape to form r the said frame, the piecesalong one side of 1 j clip extending across the double portion on topand bottom and along the opposite sides of the tooth, the ends of saidclip being threaded and nuts on said threaded ends for securing theparts in place, the construction and arrangement being such that uponloosen ing the clamp, the teeth can be adjusted vertically or slid alongthe double portion and secured in such adjusted position, substan-'tially as described. 7

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
